Operating Basics
■ If the disc is poor in quality, dirty or damaged, writing or rewriting errors
may occur. Be careful to check the disc for dirt or damage before you
use it.
■ The actual number of rewrites to CD-RW, DVD-RW, DVD+RW or DVD-
RAM is affected by the quality of the disc and the way it is used.
■ There are two types of DVD-R discs: authoring and general use discs.
Do not use authoring discs. Only general use discs can be written to by
a computer drive.
■ You can use DVD-RAM discs that can be removed from a cartridge and
DVD-RAM discs designed without a cartridge.
■ Other DVD-ROM drives for computers or other DVD players may not be
able to read DVD-R/-RW or DVD+R/+RW discs.
■ Data written to a CD-R/DVD-R/DVD+R disc cannot be deleted either in
whole or in part.
■ Data deleted (erased) from a CD-RW, DVD-RW, DVD+RW and DVD-
RAM disc cannot be recovered. Check the content of the disc carefully
before you delete it. If multiple drives that can write data to discs are
connected, be careful not to delete data from the wrong drive.
